Maintenance of _____ is an integrated process requiring optimal muscular balance, joint dynamics, and neuromuscular efficiency u
aleksandr82 [10.1K]

Answer:

Maintenance of postural equilibrium is an integrated process requiring optimal muscular balance, joint dynamics, and neuromuscular efficiency using visual, vestibular, and proprioceptive inputs.

Explanation:

Maintaining postural equilibrium involves multiple parts of the body, and can be divided in two levels of control: the first one being on the brainstem, the cerebellum and the spinal cord; and the second one including cortical areas that participate in multisensory integration and control as well as the basal ganglia located in the cerebrum.

Where do queen bees lay eggs and larval bees are fed by worker bees
steposvetlana [31]

Answer:

1. Queen bees lay their eggs after within each cell inside a honeycomb.

2. True. Worker bees feed the larvae with a combination of nutrients, from nectar and pollen to bee milk and water.

Explanation:

1. Queen bees lay their eggs after within each cell inside a honeycomb (hive) <em>[</em><u><em>See image below]</em></u><em> </em>during the winter.

The queen is able to lay over two thousand eggs PER DAY! Each egg has an approximate size of 1 mm long. This process then leads to the formation of a whole new colony of bees.

<u><em></em></u>

2. True.

Worker bees have the largest density of all, that is, there are numerous worker bees within a colony. As their name "worker" implies, they have plenty of tasks to perform. For example, they have to clean the hive regularly, ventilate it during warm conditions or keep it warm during cold conditions, and also care for the queen. However, one the most important roles of workers is to feed the larvae, during this stage they are also called "nurse bees." These bees feed the young with a combination of nutrients, from <u>nectar and pollen to bee milk and water</u>.

How does the Richter scale measure an earthquake?
USPshnik [31]

Richter's original magnitude scale (ML) was extended to observations of earthquakes of any distance and of focal depths ranging between 0 and 700 km. Because earthquakes excite both body waves, which travel into and through the Earth, and surface waves, which are constrained to follow the natural waveguide of the Earth's uppermost layers, two magnitude scales evolved - the MB and MS scales.

The standard body-wave magnitude formula is

MB = log10(A/T) + Q(D,h) ,

where A is the amplitude of ground motion (in microns); T is the corresponding period (in seconds); and Q(D,h) is a correction factor that is a function of distance, D (degrees), between epicenter and station and focal depth, h (in kilometers), of the earthquake. The standard surface-wave formula is

MS = log10 (A/T) + 1.66 log10 (D) + 3.30 .

There are many variations of these formulas that take into account effects of specific geographic regions so that the final computed magnitude is reasonably consistent with Richter's original definition of ML. Negative magnitude values are permissible.
